The Wrecking Ball hitmaker announced the sad news via her Twitter.com page, sharing pictures of her beloved pet dog Floyd, an Alaskan Klee Kai, and writing, "Today is the 2nd (second) worst day of my life... I don't wanna say it because I don't want it to be real... But my precious baby Floyd has passed away. I am broken... I know I don't mean it but I wish he would've taken me with him. This is unbearable. What am I gonna do without him?"

Cyrus also apologised to the audience of her upcoming concert in Boston, Massachusetts on Wednesday (02Apr14), adding, "I'm sorry in advance if I am not myself... Boston. I will try my best to be my best."
